Pilots' families blame aircraft fumes for deaths

Richard Westgate lived for flying. But the British Airways pilot from Dorset died in December after suffering years of chronic fatigue, mood swings and then a fall. Then another BA pilot, Karen Lysakowska from Surrey, died after developing cancer.

Both were in their early forties, and believed they'd been repeatedly exposed to toxic fumes in the cockpits of the planes they flew. The air supply comes from a bleed pipe off the jet engine. More on this story shortly.
